Extraction and Migration Study of 12 Common Antioxidants in the Medicinal Composite Film of Pediatric Antitussive Oral Liquid for Children
An ultra-high performance liquid chromatography-tandem mass spectrometry(UPLC-MS/MS) method was developed for the determination of 12 common antioxidants in pediatric antitussive oral liquid and its packaging material(oral liquid medicinal composite film). The chromatographic column used was Shim-pack GIST C
18
(100 mm×2.1 mm,2 μm),with methanol(containing 0.01 mol/L formic acid and ammonium formate) and water(containing 0.01 mol/L formic acid and ammonium formate) as the mobile phase by gradient elution. Electrospray ionization(ESI) and multiple reaction monitoring(MRM) in positive ion mode were employed for qualitative and quantitative analysis. The results showed good linearity for the 12 antioxidants in the concentration ranges of 10 ng/mL to 400 ng/mL,with correlation coefficients(
r
) not less than 0.996 3. The detection limits of extraction and migration were in ranges of 0.40-13.25 ng/g and 1.01-33.13 ng/mL,and the quantitative limits were in ranges of 1.35-44.17 ng/g and 3.37-110.42 ng/mL,respectively. The recoveries ranged from 80.1% to 114%,and the relative standard deviations(RSDs,
n
=3) were between 1.5% and 7.2%. Migration of antioxidants 1010 and 168 was detected in the medicinal solution,but their levels were below their respective permitted daily exposure(PDE),posing minimal impact on the safety risk of the medication. The method is highly efficient,sensitive,accurate,reliable,and easy to operate,making it suitable for the determination of 12 common antioxidants in pediatric antitussive oral liquid and its packaging material.
